> Key: ASTERIXDB-3255
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3255
> Project: Apache AsterixDB
> Issue Type: Improvement
> Components: EXT - External data
> Affects Versions: 0.9.9
> Reporter: Wail Y. Alkowaileet
> Assignee: Wail Y. Alkowaileet
> Priority: Major
> Labels: triaged
> Fix For: 0.9.9
>
>
> The current implementation of dynamic prefixes requires that declared
> computed fields should also appear in the external datasets' records. In
> certain use cases, computed fields may not have the same values or they may
> have a different JSON path or type. Those cases should be handled by
> embedding the values of computed fields.
